    First of all its not an assignment, its a review for my test...

    Here are the questions (from 5-10; disregard circuit 3):

    I'm just confused with those questions:

    I already know the basic formulas of Beta, Alpha, Vth, Rth, ohm's law representation of Ib, Ic and Ie, and more, I just don't know how to answer those questions.

    I even don't know what "S" means (in number 10)...!

    Please help, I beg of you, because I failed in my first test about diodes, I don't want to fail this again.

    Thanks in advance... :)

    You need to show as your attempt to the problem first.
